'I'm not afraid of the fanny pack': Matthew McConaughey tries to bring maligned accessory back into fashion at ball game

And now Oscar winner Matthew McConaughey has decided to try to use his influence to bring the humble fanny pack back into fashion.

The Texas Buyers Club star showed off his generously sized pouch while watching the Red Sox play in Boston on Sunday with his son Levi, who is thankfully too young to know any better.

Matthew, 44, looked every inch the stylistically challenged middle-aged father as he watched the Houston Astros humiliate the Red Sox 8-1 in their own backyard at Fenway Park.

After being questioned on his look by a reporter he said: 'I'm not afraid of the fanny pack.

'You gotta kind of put it on the side to make it look a little not as nerdy, but still, practicality wins out.

'I got so much gear in here that I don't want in my pockets.'

The 44-year-old even tried to persuade the intrepid correspondent to wear a Texas-flag-emblazoned fanny pack she confessed to him she owned, saying: 'Keep wearing it, keep wearing it.

'They're on the way back. Some decade from now.'

While Matthew was proud to be wearing it in the present, another star made waves after showing off his own fanny pack from the past.

For Dwayne Johnson sent his legion of fans into a frenzy when he posted a picture of himself wearing one of the accessories.

The artist formerly known as The Rock showed off his classic 90s look in an Instagram post he made for Throwback Thursday a few weeks ago, with the chuffed Hercules favourite saying, 'Fanny pack and lean take it to a whole other level.'
